The Blue Heaven have a more "forward" presentation, and a little emphasis to the midrange compared to the Red Dawn, which is more even/flat/neutral; yada yada yada...
A tuner is not going to have real deep bass or dog whistle highs like a CD player or LP setup. You should maybe try to borrow a pair of Red Dawn to try first, and make up your own mind. But my guess without listening is to stay with the Blue Heaven. You may find the Red Dawn just brings out the shortcomings in FM broadcasts.
You may also find the Red Dawn a little dry in comparison, depending on your setup.
